IMPROVEMENT IN VENTILATORS FOR RAILROAD-CARS.

Specification forming part of Letters Patent No. 145,760, dated December23, 1873; application filed December 12, 1873.

To all whom it may concern:

Be it knownthat I, JASON D. SIMMONS, of Quincy, in the county of Adamsand State of Illinois, have invented a certain new and useful AutomaticOar-Ventilator, Dust and Ginder Fender; and I do hereby declare that thefollowing is a full, clear, and exact descriptionthereof, that willenable others skilled in,

the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

In the drawings, Figure 1 is a front view of my invention, and Fig. 2 atop View.

My invention has relation to automatic ventilators and dust and cinderexcluders for railroad-cars; and it consists in the construction andnovel arrangement of hinged wings attached to the outside of a car oneitherside ofa window, and so connected that one may be turned outward,while the other falls back toward the car, substantially as hereinaftermore fully described.

Referring to the drawings, A designates a car-window, having hinged toits frame the wings B, which extend to about the top of the lower sash,or may extend the whole length of the window, and are provided with lugsE, turned inwardly on their upper ends, as shown. C is a rod, having itsends bent down, and threaded to hold nuts D. This rod connects the twowings B, the ends passing down through holes in the lugs E. The nuts areput on said ends below the lugs.

WVhen the cars are in rapid motion, the forward wing is turned towardthe window at an angle of about forty-five degrees, the air acting as aresistant. In this position thewing is held, the lug preventing it fromclosing against the window. The back wing is pushed toward the side ofthe car through the medium of the connecting-rod. The projecting wingguards the window against the entrance of dust or cinders, and, bycreating'a vacuum behind it, efi'ects the perfect ventilation of thecar.

As additional security against the entrance of dust and cinders throughthe car-window, a flange, E, is turned on the outer edge of each wing,as shown, and the ends of the wings extended, as shown, some distancebelow the bottom of the window.

Having fully described my invention, I claim- 1. The wings 13, havingthe flanges E turned on their outer edges, substantially as and for thepurpose specified. v

2. The wings B, having the inwardly-turned lugs E and outwardly-turnedflanges E, and connected by means of the rod 0, substantially as shownand described.

In testimony that I claim the foreging, I

have hereunto set my hand this 5th day of- February, 1873.

JASON D. SIMMONS.
